Carpenter Ants Attack Foam Insulation

Image Description: this picture was taken during a home inspection in Vancouver, WA. What you are seeing is Carpenter Ants that have infested rigid foam insulation. When in the crawl space, the inspector could not see any dead Carpenter Ants, or any blatant damage. The only thing that inspector saw was fine dust, but it wasn't wood dust. This lead the inspector to pull back a section of the foam insulation to find the Carpenter Ants. What is interesting about this situation is that there were no signs anywhere that the Carpenter Ants had actually gone for the wood: they seemed quite happy with the insulation.

Random thing is I was researching foam insulation to get done on my house and came across something you posted. You remember my house you inspected? Is foam insulation a good thing to get sprayed in the walls? My house is always freezing and the walls are actually cold to the touch.Do you know anyone who is a professional that does this?
